Hello everyone, I'm glad to be a part of this forum 
My story goes like this: I have bought at discount a new Dahua setup which is the following:
1x NVR4108HS-EI
8x IPC-HDBW5541R-0280B-S3
Manual says that this NVR provides 1 FD/FR (face detection/face recognition) channel which works perfectly well (AI by recorder) but then it also promises that it can accept more FD channels so I've spent the whole day trying to get FD to work, yet I'm not able to
No matter what I do, I can't seem to turn off IVS/VIDEO METADATA to enable FACE DETECTION...each time I do it and hit 'apply' and refresh the page, it's back to IVS/VIDEO and other options are grayed out (FD included)
I've tried web viewer and SMARTPSS alongside NVR menu to change it but nothing helps
Am missing something or it's just not possible to set more than 1 FR channel in this setup? And if it's not possible, what is the use of FD on these cameras?
Thank you
Mirel
